CuNi8 NC012 CuNi Alloy Electric Heating Wire With Low Resistivity 0.49 μΩ·Cm
Product Introduction
CuNi8 wire (NC012) is a copper-nickel resistance alloy wire, mainly composed of copper and 8% nickel. It has a low resistivity of about 0.49 μΩ·cm and can work stably at temperatures up to 200°C. The tensile strength of CuNi8 wire is usually around 270 MPa, the yield strength is about 110 MPa, and the elongation remains above 25%, showing good mechanical properties and plasticity. In addition, CuNi8 wire also has good processing properties, is easy to draw into wire, and its mechanical properties can be optimized by appropriate annealing treatment. In terms of application, CuNi8 wire is widely used in the electronic and electrical fields, such as manufacturing resistors, potentiometers, resistor networks, terminals, low-resistance resistors, heating wires and resistance wires. Its excellent corrosion resistance and oxidation resistance make it also have certain applications in marine engineering and chemical industries, such as contact materials in submarine cables and ship electrical systems. These characteristics of CuNi8 wire make it an ideal choice for applications such as high-precision resistor elements and sensors.
